Vegetables foods are contaminated with heavy metals by different routes, being a risk to the health of the consumer. In this study was performed the quantification of heavy metals cadmium (Cd), lead (Pb), mercury (Hg) and arsenic (As) in fresh tubers of three potato varieties of Solanum tuberosum L. (potato): canchan, huayro and yellow. The samples were randomly collected from 15 stalls in the wholesale market of Santa Anita, province of Lima (Lima - Peru) all from the province of Ambo, department of Huánuco (Peru); 15 samples were collected from each variety with a total of 45 samples. The quantification of Cd and Pb was performed by Inductively Coupled Plasma Mass Spectrometry (ICP-MS), meanwhile, for the quantification of Hg and As, was used Atomic Fluorescence Spectrometry (AFS).. The Hg concentration ranged from 0,0983 to 0,2594 mg / Kg; Cd from 0,0073 to 0,0287 mg / Kg; Pb from 0,...
